Specification of Letters Patent.

Patented Oct. 24:, 1911.

Application filed November 2, 1910. Serial No. 590,301.

To all whom it may concern:

Be it known that I, ISAAC KELLY KING,-

a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Photographic-Plate Racks; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to photographic apparatus, and more particularly to a rack for the washing of photographic plates in water after they have been removed from the camera and the negative has been developed. In the washing of such plates in an ordinary sink without suitable supporting means the plates are apt to come in contact so that their surfaces are not cleaned perfectly, or are apt to become broken by rough handling or accidental movement in the sink or other receptacle.

My invention comprises a simple and compact rack upon which a large number of plates of various sizes may be carried in a slanting position, so as to be out of con tact with each other and so as to be easily removed one at a time from the bath.

In the accompanying drawings illustrating my invention Figure 1 is a perspective view illustrating a rack with a number of suspended plates carried thereon; Fig. 2 is a perspective view of a preferred form of rack employed and illustrated in Fig. 1; and Fig. 3 is a vertical transverse section illustrating a large number of plates carried by the rack.

The rack 1 illustrated in the drawings may be constructed of any desired convenient material, that shown representing pressed sheet metal. The rack comprises a foot or end portion 2 provided with steps 3 formed preferably by corrugations in the inclined sheet metal side of the foot por tion 2. The side portions 4 of the rack extend perpendicularly to the foot portion 2 and are provided with the stepped or notched upper margins 5 containing the notches 6 of any desired number.

The notches 6 are preferably arranged in series in the sloping steps or divisions 7 of the side portion 1 so as to resent a reat variety of elevations from t e base of the rack. The notches 6 are adapted to receive the cross rods or bars 8 which extend transversely across the rack and support the up per edges of the plates 9 as lllustrated in the drawings. The side portions 4 are preferably braced by the connecting panel or plate 10 to form a complete and durable box-like structure.

It will be apparent from an inspection of the drawings illustrating one form or embodiment of my invention that the photographic plates 9 may be conveniently suspended or carried on the corrugations or steps 3 of the foot portion and the cross rods 8 in large numbers without coming in contact with each other. Thus Fig. 3 illustrates four photographic plates varying in size but supported in a slanting position so as to be entirely separated from each other and easily available for removing from immersion in the water bath. By the employment of a plurality of steps 7 in the side portion 4: I provide for a greater variety of levels or heights of the notches 6 without bringing them too close together, thereby increasing the capacity of the rack.

As the plates are carried in a slanting position, and still out of contact, on the rack, they are readily freed of the adhering chemicals in the bath. The rack may also be used as a drying rack, in which case the situation of the plates leads to rapid drying.

While I have illustrated a preferred embodiment of my invention it will be understood that obvious modifications in the material of which it is constructed and the relative arrangement of the parts can be made without departing from its spirit.

What I claim is:

1. A photographic plate rack, comprising inclined and oppositely disposed side portions each provided with a series of notches in its upper margin adapted to receive supporting rods, and a foot portion end-wise disposed relative to said side portions and provided with means for supporting the ends of a plurality of photographic plates at varying levels, substantially as described.

2. A photographic plate rack, comprising oppositely disposed side portions each hav ing an inclined upper margin provided with a series of notches, a foot portion at the end of the rack having steps adapted to support one end of a plurality of photographic plates at different levels, and removable rods fitting in said notches and arranged to support the opposite ends of said plates at varying levels.

3. A photographic plate rack, comprising oppositely disposed side portions each having a plurality of inclined stepped portions, of which are supported by said rods away 10 said stepped portions having notches in from and yet above said foot portion.

their upper margins and removable support- In testimony whereof, I the said ISAAC ing rodls adaotked todextend between said KELLY KING have hereunto set my hand.
